SAN BERNARDINO --The procession led by San Bernardino County Sheriff's officials in honor of fallen Deputy Jeremiah MacKay has arrived at the San Manuel Amphitheater, where services will be held.

Sheriff's officials, followed by law enforcement agencies from numerous cities, escorted a hearse carrying MacKay's body 13 miles from the Mt. View Mortuary and Cemetery in San Bernardino.

MacKay's body will be escorted back to the mortuary following the service.

Law enforcement, friends, families and supporters gathered this morning at the Mortuary and along the procession route to pay tribute to MacKay, who was killed Feb. 12 during a manhunt for former Los Angeles police Officer Christopher Dorner.

Officers from numerous California cities and as far as Arizona and Nevada are participating in today's tribute to MacKay.

American Medical Response and Fire personnel are following at the end of the procession.

Many mourners, several holding signs, have joined police and fire agencies on overpasses along the 10 and 210 freeways to pay tribute to MacKay.

A group of more than 30 people gathered on the 210 freeway overpass at Summit Avenue.

Many people wiped tears away and saluted the hearse carrying MacKay's body as the procession passed.

Signs reading, "You're our hero," "God Bless MacKay," and "Thank you Deputy MacKay" could be seen from the freeway.

Veronica Zeigler, whose husband is a sergeant with the Sheriffs Department, brought her goddaughter out to pay tribute to MacKay.

"Anytime someone in law enforcement dies you feel you've lost a member in your family," Zeigler said.

"As a cop's wife, this is your worst nightmare come true. I want her to know we support her."

Many motorists pulled over to the side of the freeway to watch the procession.

Fred Price, a Fontana resident and former Sheriff's deputy, took his grandchildren to watch the procession.

"We're all here for the same reason -to pay tribute. He died a hero," he said.

"He not only gave his life but his wife, kids, family, friends are going to miss him."

Others stood outside the mortuary this morning as law enforcement and MacKay's family arrived.

"It's difficult when you lose somebody to a senseless killing like this," said Josh St. Ives, whose a member of the Patriot Guard Riders, a motorcycle club whose members typically attend funerals for members of the U.S. armed forces.

The Patriot Guard also participated in the Feb. 13 funeral for Michael Crain, a Riverside police officer who was also killed by Dorner during an ambush on Feb. 7. St. Ives said while it has been a tough week, he gained strength watching Crain's wife speak at her husband's funeral.

Tracy Troncoso, 47, of San Bernardino took her 7-year-old granddaughter and 6-year-old son to the nearby St. Bernardine Medical Center to watch the procession.

"We got up at 6 o'clock in the morning. I really just wanted them to come and give their respects and see all the law enforcement," Troncoso said.

Troncoso said she and her kids watched the manhunt for Dorner.

Looking to them, she said, "Aren't you guys glad that the bad guy left?"

Troncoso said her kids were scared during the manhunt, but the great show of law enforcement at the mortuary, with their lights flashing, has comforted them.

"When the widow sees all these officers from all over California paying respects, it will ease her heart, knowing he was great," she said.
